leetcode tips for beginners

if you're just getting started with leetcode and technical interviews, here are some tips. start with the basics. don't jump into hard problems right away: - arrays and strings - hash maps - two pointers - binary search consistency over intensity. it's better to solve 1-2 problems daily than to binge 20 problems in one day. understand, don't memorize. focus on understanding the patterns, not memorizing solutions.
